Application filed September 8, 1914. Serial No. 866,520.

7 To all whom it may concern:

Be it known that I, ELIAS F. YOUNCE, a citizen of the United States, residing at Union, in the countyof Montgomery and State of Ohio, have invented a new and useful Improvement in Convertible Hay-Racks, of which the following is a specification.

This invention relates to new and useful improvements in convertible hay-racks.

T heobj ect of my invention is to provide a strong and readily assembled hay-rack which may be easily and quickly converted into a wagon box, and vice versa. i

' In the accompanying drawings, Figure 1 is a perspective View of the hay-rack before its conversion into a wagon box. Fig. 2 is a perspective view, showing thebottom portion of my invention. Fig. 3 is a perspective view of my construction after'itsconversion into a wagon box. Fig. 4: is a side view of the swinging portion of my retention hinge. Fig. 5 is a bottom view of the same; Fig. 6 is a side view of the stationary portion of the retention hinge. Fig 7 is abottom view' of the same. And Fig. 8 is an elevational view, showing the two parts of the hinge connected together.

Throughout the specification and draw.

ings, similar reference characters denote corresponding parts.

In a detailed description of my invention,

the numerals 11 designate two longitudinal beams which are inclined toward each other andxjoined together at one end-by a Also supporting the'bottom 6, and "extending a short distance beyond the side edges there-i of, are transverse members 7 These members 7 as well as the connecting member 2 and cross pieces 3 and 4, are readily secured to the beams 1'-1 by angle irons 8. Truss rods 8 connected to the end transverse members 7, pass under the cross piece 4 to cooperate with the angle irons 8 in making the beams 11 and connected parts a firm and compact supporting structureforr the combined hay-rack and wagon bottom 6.

Firmly secured to one end of the bottom 6, by angle irons 8, is an upright end member 9. There is also provided a pair of side members 101O which are hingedly secured to the bottom 6 bythe following means: Referring to Fig. 4:, the numeral 11; desig-. nates, an elongated metallic plate or casting having, the outline of a dipper. The upper straight edge of the casting 11 terminates at one end in a notched portion 12, the lower edge of said casting having a wide semicircularcurve from thenotched portion 12 to a pointalmost midway its length, whence it extends in a slightly curvedlineto the opposite end of the casting. Provided in the upper central portion of the semi-circa lar part of" the casting ll, is a conical projection 13 containing a conical bore 1 1 which extends on through the casting. Below the. bore 14 is a raised segmental portion 15 which contains a circumferential slot 16.

Provided on either side of the slot 16, near the end thereof which is adjacent thenotched portion 12, is an upturned lug'17 for a pur; pose to be hereinafter explained. (See Figs. 1 and Preferably integral with, and at right angles to the faceof the casting 11, is a J longitudinal flange portion 18 provided with holes 19, and by means of bolts 20 pass: ingthrough these holes the casting 11 may be firmly secured to a side member 10. (See Fig. 5 and 8). 1 v

Referring to Fig. 6, the numeral 21 desig-' nates an elongated casting whose contour may best be described by starting at an upturned lug 22, then proceeding in a straight line to a point 23, then at a right angle to a point 24r,and thencein a straight line to a point25. Preferably integral with the casting 21, and extending outwardly at right angles thereto between the points 24 and 25, is an ear 26 adapted to rest upon a trans verse member 7 to which the casting is secured. From the point 25 to a point 27 immediately below it, the edge of the casting 21 is almost ,a semicircle," and from the point 27 to a point 28, a straight line. Between the points 28 and 22 the edge of said casting is irregularly curved to-provide a neck portion 29 which may be firmly secured to a' transverse member 7 by a bolt 30 passing through an aperture 31.. (See Figs. 6 and 8). Just below the point 23, the casting 21 has a conical projection or pivot, 32 which, is

adapted to loosely enter the bore 14 in tho casting 11 for the purpose of supporting'the hereinafter described.

About midway between the points 25 and 27, just inside the semicircular edge ofthe casting 21, is an upturned lug 33 which cooperates with the lug 22 in eifecting'a result to be hereafter explained.

Beneath and a little to the right of the pivot 32, is a circular aperture 34: which receives a bolt 35, one end of which is secured to a transverse member 7, while the other, after passing through the aperture 3t,-is adapted to loosely enter the slot 16 in the casting 11. The bolt 35 has a head 35 which is adapted to engage the upturned lugs 17 to hold the casting 11 in a vertical position, while the other end of the bolt 35 passes through its respective transverse member 7 to receive a winged nut 36. (See Figs. 1, 2 and 8). v

In operation, by means of the bolt'30 and car 26, a casting 21 is secured to each transverse member 7 in such a manner as to cause the pivot 32 to assume a position slightly beyond the side edge of the bottom 6. (See Figs 1, 3 and 8). The castings ll, of which there is one for every casting 21, are secured to the side members 101O by the bolts 20 which extend through the apertures 1.9 in their flange portions 18. (See Figs. 3 and 8). The two separate castings 21 and 11 are united by causing the pivot 32 of the former to pass through the bore 14 of the latter, and to prevent said castings from becoming disengaged, a nut 37 may be screwed on the end of a bolt 38 which passes through the transverse member 7and a hole 39 in the pivot When the casting 11 has been pivotally mounted upon the casting 21, there is formed for the side members 1010 a retention hinge whose movement will now be described. As has been stated, the castings 21 are firmly secured to the transverse mem bers 7 which support the bottom 6, While the castings 11 are attached to the side members 10-10. iherefore, it will be seen that said side members may be moved about the pivots 32 from their lower or hay-rack position shown in Fig. 1, to their vertical or wagon-box position shown in Fig. 3.

The lowermost or hay-rack position of the castings 11 and side members 1010 which they support, is shown in Figs. 1 and 8. In this position the lugs 33 engage the lower edges of the castings 11, the lugs 22 at the same time engaging the notched. portions 12 of said castings, to arrest a further downward movement of the latter. This construction makes it possible for the side members 1010 to support a great weight in their lateral positions.

When the casting 11 is turned about the pivot 32 from the hay-rack to the wagon boX position, the bolt 35 is loosened by turning the winged nut 36, as the head 35 of said bolt lies in the path of the lugs 17 which move upwardly with the slot 16.

Therefore, by drawing the bolt 35 outwardly, the head thereof will clear the lugs 17 during their upward movement. WVhen the castings 11 and side members 1010 which they support, attain their vertical or wagonboX position, the bolts 35 will be in the eX- treme lower ends of the slots 16. Accordingly, if it is now desired to maintain said side members in their elevated position, the winged nuts 36 should be turned sufficiently to draw the heads 35 of the bolts 35 inwardly a sufiicient distance to lie in the path of the lugs 17 to engage the latter and thereby arrest a downward movement of the castings 11 until a hay-rack position of the side members 1010 is again desired. It will now be seen that the side members 1010 will be firmly held in their lowermost or hay-rack position by the lugs 22 and 33 engaging the castings 11; that said castings may be freely turned about the pivots 32 to bring said side members into a vertical or Wagon-box position, and that theyv may be firmly held in such a position by the slot and bolt construction just de scribed. Thus, by the use of my improved parts, one attached to the bottom member and the other secured to a side member, means for pivotally securing the last named part to the first named one, lugs on the first named part to limit the movement of the second named part in one direction, and. a single slot, pin and shoulder mechanism for limiting the movement of the last named part in the opposite direction, substantially as described.

In testimony whereof I have hereunto set my hand this 5th day of September, 1914.
